The existing `extern "C"` etc. may change behavior for cross-language unwinding in a future release. * Update the version of musl used on `*-linux-musl` targets to 1.2.3 enabling time64 on 32-bit systems. * Stabilize `debugger_visualizer` for embedding metadata like Microsoft's Natvis. * Enable flatten-format-args by default. * Make `Self` respect tuple constructor privacy. * Improve niche placement by trying two strategies and picking the better result. * Use `apple-m1` as the target CPU for `aarch64-apple-darwin`. * Add Tier 3 support for the `x86_64h-apple-darwin` target. * Promote `loongarch64-unknown-linux-gnu` to Tier 2 with host tools. Refer to Rust's [platform support page][platform-support-doc] for more information on Rust's tiered platform support. ## Libraries * Rework handling of recursive panics. Additional panics are allowed while unwinding, as long as they are caught before escaping a `Drop` implementation, but panicking within a panic hook is now an immediate abort. * Loosen `From<&[T]> for Box<[T]>` bound to `T: Clone`. * Remove unnecessary `T: Send` bound in `Error for mpsc::SendError<T>` and `TrySendError<T>`. * Fix docs for `alloc::realloc` to match `Layout` requirements that the size must not exceed `isize::MAX`. * Document `const {}` syntax for `std::thread_local`. This syntax was stabilized in Rust 1.59, but not previously mentioned in release notes. ## Stabilized APIs * `CStr::is_empty`](https://doc.rust- lang.org/stable/std/ffi/struct.CStr.html#method.is_empty) * `BuildHasher::hash_one`](https://doc.rust- lang.org/stable/std/hash/trait.BuildHasher.html#method.hash_one) * `NonZeroI*::is_positive`](https://doc.rust- lang.org/stable/std/num/struct.NonZeroI32.html#method.is_positive) * `NonZeroI*::is_negative`](https://doc.rust- lang.org/stable/std/num/struct.NonZeroI32.html#method.is_negative) * `NonZeroI*::checked_neg`](https://doc.rust- lang.org/stable/std/num/struct.NonZeroI32.html#method.checked_neg) * `NonZeroI*::overflowing_neg`](https://doc.rust- lang.org/stable/std/num/struct.NonZeroI32.html#method.overflowing_neg) * `NonZeroI*::saturating_neg`](https://doc.rust- lang.org/stable/std/num/struct.NonZeroI32.html#method.saturating_neg) * `NonZeroI*::wrapping_neg`](https://doc.rust- lang.org/stable/std/num/struct.NonZeroI32.html#method.wrapping_neg) * `Neg for NonZeroI*`](https://doc.rust- lang.org/stable/std/num/struct.NonZeroI32.html#impl-Neg-for-NonZeroI32) * `Neg for &NonZeroI*`](https://doc.rust- lang.org/stable/std/num/struct.NonZeroI32.html#impl-Neg-for-%26NonZeroI32) * `From<[T; N]> for (T...)`](https://doc.rust- lang.org/stable/std/primitive.array.html#impl-From%3C%5BT;+1%5D%3E-for-(T,)) (array to N-tuple for N in 1..=12) * `From<(T...)> for [T; N]`](https://doc.rust- lang.org/stable/std/primitive.array.html#impl-From%3C(T,)%3E-for-%5BT;+1%5D) (N-tuple to array for N in 1..=12) * `windows::io::AsHandle for Box<T>`](https://doc.rust- lang.org/stable/std/os/windows/io/trait.AsHandle.html#impl-AsHandle-for- Box%3CT%3E) * `windows::io::AsHandle for Rc<T>`](https://doc.rust- lang.org/stable/std/os/windows/io/trait.AsHandle.html#impl-AsHandle-for- Rc%3CT%3E) * `windows::io::AsHandle for Arc<T>`](https://doc.rust- lang.org/stable/std/os/windows/io/trait.AsHandle.html#impl-AsHandle-for- Arc%3CT%3E) * `windows::io::AsSocket for Box<T>`](https://doc.rust- lang.org/stable/std/os/windows/io/trait.AsSocket.html#impl-AsSocket-for- Box%3CT%3E) * `windows::io::AsSocket for Rc<T>`](https://doc.rust- lang.org/stable/std/os/windows/io/trait.AsSocket.html#impl-AsSocket-for- Rc%3CT%3E) * `windows::io::AsSocket for Arc<T>`](https://doc.rust- lang.org/stable/std/os/windows/io/trait.AsSocket.html#impl-AsSocket-for- Arc%3CT%3E) These APIs are now stable in const contexts: * `<*const T>::read`](https://doc.rust- lang.org/stable/std/primitive.pointer.html#method.read) * `<*const T>::read_unaligned`](https://doc.rust- lang.org/stable/std/primitive.pointer.html#method.read_unaligned) * `<*mut T>::read`](https://doc.rust- lang.org/stable/std/primitive.pointer.html#method.read-1) * `<*mut T>::read_unaligned`](https://doc.rust- lang.org/stable/std/primitive.pointer.html#method.read_unaligned-1) * `ptr::read`](https://doc.rust-lang.org/stable/std/ptr/fn.read.html) * `ptr::read_unaligned`](https://doc.rust- lang.org/stable/std/ptr/fn.read_unaligned.html) * `<[T]>::split_at`](https://doc.rust- lang.org/stable/std/primitive.slice.html#method.split_at) ## Cargo * Allow named debuginfo options in `Cargo.toml`. * Add `workspace_default_members` to the output of `cargo metadata`. * `cargo add` now considers `rust-version` when selecting packages. * Automatically inherit workspace fields when running `cargo new`/`cargo init`. ## Rustdoc * Add a new `rustdoc::unescaped_backticks` lint for broken inline code. * Support strikethrough with single tildes.](https://github.com/rust- lang/rust/pull/111152/) (`~~old~~` vs. `~new~`) ## Misc ## Compatibility Notes * Remove structural match from `TypeId`. Code that uses a constant `TypeId` in a pattern will potentially be broken. Known cases have already been fixed -- in particular, users of the `log` crate's `kv_unstable` feature should update to `log v0.4.18` or later. * Add a `sysroot` crate to represent the standard library crates. This does not affect stable users, but may require adjustment in tools that build their own standard library. * Cargo optimizes its usage under `rustup`. When Cargo detects it will run `rustc` pointing to a rustup proxy, it'll try bypassing the proxy and use the underlying binary directly. There are assumptions around the interaction with rustup and `RUSTUP_TOOLCHAIN`. However, it's not expected to affect normal users. * When querying a package, Cargo tries only the original name, all hyphens, and all underscores to handle misspellings. Previously, Cargo tried each combination of hyphens and underscores, causing excessive requests to crates.io. * Cargo now disallows `RUSTUP_HOME` and `RUSTUP_TOOLCHAIN` in the `[env]` configuration table. This is considered to be not a use case Cargo would like to support, since it will likely cause problems or lead to confusion. ## Patch Instructions: To install this SUSE Moderate update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
